Errant down-arrow key on Magic Keyboard

[Crowbot]

I just noticed that the down-arrow key on my A1644 Magic keyboard is not working correctly. Instead of down-arrowing all I see is the cursor moving to the right. I can't find anything on this online. Any ideas?

Have you recently made any assignment keyboard changes to the Magic Keyboard?

Not intentionally but I'll check that. Thanks.

Nothing I can find.
